Mashiro Kurata, a second-year student at Tsukinomori Girls' Academy, initially struggled with feelings of inadequacy among her talented peers, experiencing daily sorrow upon entering the prestigious school. Her perspective shifted after witnessing Poppin'Party's performance at CiRCLE, sparking an interest in music despite initially deeming bands "scary" and leaving dejectedly. This encounter led her to join Morfonica as vocalist and lyricist. Quiet, reserved, and shy, Mashiro exhibits negative thinking and self-doubt, fearing interactions with strangers due to concerns about poor first impressions or seeming peculiar. Her active imagination fuels vivid daydreams—such as fantasy worlds with flying whales or soaring through skies—which directly inspire her lyrics. She avoids vegetables like broccoli, peas, and carrots, dislikes spicy foods, and shuns horror-themed content. Physically, Mashiro has light blue eyes and shoulder-length whitish-blue hair, a fair complexion, and typically shy expressions. Standing 154 cm tall, her initial casual outfit features a striped dark cyan dress over a white shirt, accented by a light indigo bow, ankle-high socks, and brown Mary Jane shoes. Her theme color is light blue. As Morfonica’s vocalist and lyricist, Mashiro draws from her imaginative worlds while gradually building confidence through band activities and bandmate bonds. She befriends Rokka, sparking light-hearted arguments over their shared admiration for Poppin'Party. Mashiro enjoys knitting and adores fluffy characters like Michelle. Her development involves overcoming social anxiety and self-loathing, evidenced during band practices, joint performances, and post-concert worries about mistakes straining relationships. She participates in events like a trial-themed episode centering on a chocolate cornet embezzlement case. Mashiro transferred to Tsukinomori and felt isolated until discovering music. Her surname means "warehouse rice field," while her given name signifies "pure white." Born February 19 under Pisces, she relishes beef stew and adores the "Fairy Legends" fantasy series, particularly its marshmallow rabbit creature.
